An electron-withdrawing perfluoroalkyl group at the incipient cationic center enhances neighboring-group... Acid-Catalyzed Regioselective Sulfetherification of Alkenols and Stereoselective Rearrangement of Tetrahydrofuran to Tetrahydropyran [作者：WANG HAINING; HUANG DESHUN; CHENG DONGHAO; LI LIJUN; SHI YIAN,期刊：Organic Letters, 页码：1650-1653 , 文章类型： Article，,卷期：2011年13-7] An efficient acid-catalyzed sulfetherification of various unsaturated alcohols with sulfenamides to form tetrahydrofurans and tetrahydropyrans regioselectively is described. Mechanistic studies have shown that the tetrah... Helical Chiral 2,2 '-Bipyridine N- Monoxides as Catalysts in the Enantioselective Propargylation of Aldehydes with Allenyltrichlorosilane [作者：CHEN JINSHUI; CAPTAIN BURJOR; TAKENAKA NORITO,期刊：Organic Letters, 页码：1654-1657 , 文章类型： Article，,卷期：2011年13-7] A highly enantioselective synthesis of homopropargylic alcohols is achieved by using the new helical chiral 2,2'-bipyridine N-monoxide catalyst and allenyltrichlorosilane. This method can be further extended to the enant...
